Navien condensing tankless water heaters heat water only as you use it — no standby tank losses and no running out mid-shower. They're far more efficient than old tank systems, reaching up to 0.97 UEF, ENERGY STAR certified and backed by up to a 15-year heat-exchanger warranty.
While some tankless units only manage 2–3 gallons per minute, Navien builds some of the most powerful tankless water heaters on the market — delivering the flow rates needed to run multiple fixtures at once in a busy Long Island home.
Navien recommends using only factory-authorized installers for tankless water heaters — and that's exactly what we are. Authorized installation protects your warranty and ensures the unit performs to spec for years.
Many Long Island homes still rely on an aging tank water heater. When it's time to replace, we right-size a Navien tankless (or heat pump) unit for your household, handle the install cleanly and set you up for lower bills and endless hot water.

I have nothing but good things to say about this company and their employees! I needed emergency service at 4am and they responded within a half hour! And even at that early morning hour they were pleasant and efficient! I have since signed up for a service contract with them and am confident that the excellent service will continue.
Used them for over 6 years. Very neat professional installation and when I did have a problem they have been very responsive. Brian and his crew are professional and easy to deal with. Highly recommend!
I have been using this company for years and have recommended them to all my friends and family that needed this type of service. Have not had one person complain I gave them a bad recommendation. Great company - Great Service - Great Workers!
